Chicken, Pizza, and Tacos, Oh My! Temporal at Yum! Brands

Yum! Brands is building a next generation eCommerce Platform to power its brands: KFC, Taco Bell, Habit Burger and Pizza Hut. Processing millions of orders robustly can be a complex problem. Like, really complex. Traditional eCommerce order services often utilize state machines, databases and distributed sagas to keep track of all the various steps that an order must go through in its lifetime. Then, what about the inevitable failures? The database could become unavailable, the POS device in the store could go offline, the payment processor could have a brief outage and dozens of other scenarios. All of these could lead to a bad real-life experience for a customer waiting for their meal.

In this talk, Matt McDole steps through the "before and after" transition of the Yum Platform's ordering engine and highlight some of key benefits we got out of building on top of Temporal.
